1997 – 2004: Studies of Biology at Christian Albrechts University of Kiel with fisheries science as main subject. Diploma thesis title: “Diet selection of predators and availability of prey organsims as critical factor in multi species stock assessment- an example from the North Sea MSVPA”.

Working Group - Committee	Tasks
ICES
Working Group on Multispecies Stock Assessment Methods (WGSAM)	This working group aims at enabling research on predator-prey interactions for developing advice on the ecosystem approach to fisheries management.
Working Group on the Assessment of Demersal Stocks in the North Sea and Skagerrak (WGNSSK)	This working group provides advice on single species catch quotas (TAC). Using historical information on catches and survey indices, quantitative models are used to assess the current population size and forecast future conditions.
Advisory Committee des ICES (ACOM)	The Advisory Committee (ACOM) translates ICES science into advice on the sustainable use and protection of marine ecosystems. C. Zimmermann is the German ACOM member and A. Kempf is one of his deputies.
Advice Drafting Group (ADG) on widely distributed stocks	The scientific advice for widely distributed stocks, e.g. mackerel, is finalized in this group.
Bay of Biscay Advice Drafting Group (ADGBBI) - chair	The scientific advice for stocks in the Bay of Biscay and Iberian waters is finalized in this group.
